The means I I describes substantially The protrusionof the twisted wire through the a circle about stick I0 but is open at one side lslit in the sleeve 28maintains the `frame against where it-has spaced apart ears I2 and I3 with rotative displacementirelative to the sleeve- 28 complemental apertures vIIL-and I5 throughwhich and vit is-impossible yto move the frame at aman-55i gle to its plane without a concurrent movement of the sleeve 28 save by deformation of the twisted wire frame of the duster which deformation will not normally occur.

Moreover the eccentric distortion of sleeve 28 is maintained and resiliently supported by the cross-sectional configuration of the frame, thus facilitating the maintenance of the frame in any of the pre-arranged positions. This action is more particularly apparent in the embodiments shown in Figure 2 wherein the sleeve is distorted about a two-strand frame.

The duster is assembled by attaching duster material 32 to frame 3| and thereafter shaping the frame to provide the inset 33-therein. The

sleeve 28 is disposed about the frame material 3| at the innermost part of the'inset section.4 This part should preferably bedevoid of duster material 32 and may comprise the ends of the free frame 3|. The sleeve 28 with the twistedwire frame material protruding from the slit ink the sleeve `at each end thereof is inserted into bearing 23 and tongue 2liY drawn against arcuate section 2| by bolt 26 and nut 21. A rivet may take the. place of the bolt and nut, 26 and 21, respectively. The assembled socket and frame may then be attached to stick I0.

The bearing 23-may be covered by a felt strip 34which is generally of the same color as duster material 32l and which is held in position by rivets 35 extending across-its free ends.

In operation, the duster is vused generally in two substantially diametrically opposed positions. Either of these positions may be attained when the slit is rotated so that the sleeve 28 is moved in the bearing past the longitudinal slot which exists between the tongue 24 andarcuate section 2|. Movement of the sleeve from one extreme position to the other obtained by moving the slit in the sleeve past the slightly open section of bearing 23 is had with relatively slight friction. Once the slit in the sleeve hasbeen moved beyond the. slit in the bearing so that both of its open edges of the sleeve are within the circular portion of the bearingthere is increased friction which tends to maintain the duster frame in any selected angular position.

Such friction is sufficient to prevent accidental displacement of the frame4 from any se- ,Y lected angle selected but not suflicient to prevent an intentional change in angle from one side of the stick to the other side thereof during use.

It will be apparent that the cross-sectional configuration of the frame 3| will causev the bearing. 23 to t securely upon the sleeve 28 and assist the stop action of the sleeve 28'within the bearing 23, as well as,` the cooperation between the sleeve and the frame 3|. If the wires are twisted together in substantially triangular cross-section, as in Figures 2 to 4, a frame mate-r rial is provided which is generally symmetrical and which, therefore, supports the sleeve 28uniformly. At the same time, the support is obviously resilient and acts in large measure for the resilient engagementI of the sleeve 28 with the inner surfaces of the bearing 23; On the other hand, a double strand frame gives a greater measure of permanent distortion and is preferable where rit is distortedto cause relatively rigid lmaintenance of the frame inV either of the predetermined angular positions.

In addition, the various .configurations permit the portion of thetwires adjacent the split in the sleeve to engage therewith and prevent relativerotation. Accordingly in the present organization the different elements cooperate to enhance the control of the stop action, as well as to effectively lock the Aframe 3| in the sleeve at points along the length thereof and furthermore to provide a structure which is of considerable rigidity and strength.

The arcs in the sleeve 28 may be such that two different parts of the sleeve 28 spaced one hundred and eighty degrees apart register with the opening between tongue 24 and arcuate section 2| to provide two snap in positions, these snap in positions being generally opposed as previously stated. To dislodge the duster from either of these positions requires intentional displacement onthe part of the user.

Such parts,- eccentric to the main body of sleeve 28, may be preformed to provide seats for the long ends of frame 3| or if preferred, may be formed in sleeve 28 as sleeve 28 is closed over the ends of frame 3| in assembly. Said eccentric parts prevent slippagev of the frame ends in the sleeve 23 as heretofore pointed out.
